Zusammenfassung:	A vehicle has a forward mounted primary gasoline engine operatively engaged with the front axle and its associated wheels. The vehicle also has a rear mounted second motor drivingly engaged with the rear axle which is normally a dead axle. The rear axle is selectively drivingly engageable with the rear wheels which can overrun the rear axle in both the forward and reverse directions. The second motor is preferably an electric motor operable in two directions but alternatively may be a hydraulic pump/motor. The second motor, which may be driven by the primary motor or from an independent power source such as a battery, is manually actuable by the vehicle operator and automatically disengageable upon reaching a predetermined speed.
